This invention relates to disk grinding mathe works'upporting lever '8, It is'formed V chines commonly called disk grinders and with an angular/end portion 13 extending has for its object a particularly simple, eflitoward the lever B to engageat its end with] cient and readily operated means for acthe upperedgeofthe lever 8. The gauge lever curately determining the position of the work 11 is adjustable in difierentfradialpositions support relatively to the grinder in order to shift its vertically arranged end 14: into that the disks may be ground accurately to a different positions relatively to the lever '8 predetermined size. and it is held in itsadjusted positionby a The invention consists. in the novel features wing nut 15" threading on the pivot pin 12 and in the combinations and constructions against the leverll or itheihub' thereof.
